It has been very helpful. The user interface is not difficult to navigate. I am cancelling only because I do not have the volume of documents to warrant the cost. But when this changes I will certainly return.

good. It took awhile for me to figure out how to print it, but it thought I was on actual disability website and when found it was a fee I got discouraged because I felt it was misleading, but after I used it I felt better.

AWESOME SOFTWARE Great software, the only challenge I had was the sign in process. I have had a few accounts as I had challenges signing in and ended up making additional accounts. This could be user error but I am sure others have had this issue also.

This is a great program if you need this service. We needed it at one time, but did not realize we could do this on line. I would recommend it to anyone who is in the business of needing documents filled out, signed and delivered.

What do you like best? It is much easier to use than Adobe Acrobat. Much more intuitive functions and file management. It has saved me a ton of time with the cloud storage of documents. I have used effectively for construction related documents. What do you dislike? Very rarely I have needed to use another platform because some municipalities require it but 98% of what I need to do is supported. What problems are you solving with the product? What benefits have you realized? Remote completion of forms and extracting text from PDF documents mostly.

I have found the software to be easy to use and has features that similar sites don't have. I have not yet spent much time to learn all of its features but I plan to. I would like to create forms and sell them on your platform. I would like to create some form that would allow a business to evaluate and identify its essential functions so that they may operate efficiently in times of, say a global pandemic.
